Abstract
This study investigates the effects of seasonal changes in vegetation productivity on olive baboon feeding behavior in a protected Guinea savannah (Kainji Lake National Park). Over two consecutive years (2017 and 2018), observations were conducted both during the wet and dry seasons using a scan sampling method. Results revealed that olive baboons consumed 34 plant species belonging to 20 families, with 28 species in the wet season and 12 in the dry season. A total of 922 feeding events were recorded in the wet season and 621 in the dry season, indicating significant seasonal variation. Fruits were the preferred food item, especially in the dry season, followed by animal matter, seeds, leaves, and subterranean food. Interestingly, baboons also consumed tree bark regardless of season. In addition, their consumption of fruits (in both seasons) and seeds (in the dry season) highlights their ecological role in seed dispersal and plant regeneration within the park. To sustain baboon (and all non-human primates) conservation efforts within the park, it’s important to maintain a high diversity and abundance of native fruit trees throughout the year. This study highlights the importance of understanding how seasonal changes in vegetation affect olive baboon feeding behavior for effective park management and biodiversity conservation.
期刊介绍:
Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
